Free · In‑App Purchases

Private AI for you. Record notes, generate natural audio, and build searchable Knowledge Libraries. Chat with local or cloud models. Your data, your rules. Turn every project into a private AI workspace. Record voice notes, analyze documents, collaborate with AI teams, and chat with powerful local or cloud models, all while keeping your data under your control. Private & Powerful AI: Your Choice Transform speech to text and chat with advanced AI models without sending data away. Run leading open-source models 100% offline or connect to cloud providers when you need extra power. - 100% On Device: Run top models like Llama, Gemma, Phi, Qwen, and DeepSeek locally, optimized for Apple Silicon with MLX and Llama.cpp Engine. - Cloud Capable: Optionally connect to providers like OpenAI, Anthropic, Gemini, Groq, OpenRouter, LM Studio, and Ollama in one unified interface. - Hybrid Workflow: Switch between local and cloud models inside the same conversation, maintaining clear data ownership. Knowledge Libraries for Serious Projects Version 1.33.0 introduces Knowledge Libraries, a dedicated AI memory for each project, client, or research topic. Group the right files and let your AI assistant focus only on the context that matters. - Create a Library for each project to group PDFs, notes, web captures, and images. - Use "library aware search" so answers are sourced directly from your active Library. - Manage all Libraries from a single view with document previews and metadata. Collaborative AI Teams Create sophisticated AI teams where specialized agents work together on complex tasks. Move beyond single-turn chats with multi agent workflows. - Deploy built in teams for business strategy, academic research, and creative projects. - Example: Use a "Market Analyst" + "Strategic Planner" + "Risk Assessor" team for business planning. - Configure custom multi agent flows with decision making processes, perfect for complex problems. Complete Voice, Speech & Translation Suite Capture ideas and create professional audio with a full voice workflow. - Instantly record and transcribe meetings, lectures, or voice notes. - Generate natural, professional quality speech from any text using Apple voices or the advanced Kokoro voice engine. - Effortlessly translate languages and get AI generated summaries with natural voice narration. - Reuse previous recordings with different models for new summaries or deeper analysis. Smart Document, Vision & Web Understanding Bring external knowledge into your AI workflow securely. - Use local vision models to understand photos, diagrams, and screenshots on-device. - Tap into cloud vision models for even richer analysis when you choose. - Analyze PDFs, text files, and images with OCR to extract insights and summarize reports. - Use built in web search and page by page reading mode to let AI read sources and return structured answers. Deep Apple Ecosystem Integration Enjoy a native experience across iPhone, iPad, and Mac, optimized for Apple Silicon. - Launch AI instantly from the Mac menu bar or with system wide hotkeys. - Use Siri and Shortcuts to trigger AI commands and quick actions. - Connect your iPhone or iPad to your Mac for a seamless cross platform workflow. - Clone conversations, run variations, and keep temporary chats for quick experiments. Designed for You Whether you're developing business strategies with AI teams, building a Knowledge Library for research, creating audio content, or analyzing documents. On-Device App gives you the tools to do it your way. Work 100% offline for complete privacy, or connect to powerful cloud models when you need them. It's your data, your projects, and your choice.
